Analysis of Model Results for the Turning of the Wind and Related Momentum Fluxes in the Stable Boundary Layer [PDF]
, 2009 The turning of wind with height and the related cross-isobaric (ageostrophic) flow in the thermally stable stratified boundary layer is analysed from a variety of model results acquired in the first Global Energy and Water Cycle Experiment (GEWEX ...

The minimal seed of turbulent transition in the boundary layer [PDF]
, 2011 This paper describes a scenario of transition from laminar to turbulent flow in a spatially developing boundary layer over a flat plate. The base flow is the Blasius non-parallel flow solution; it is perturbed by optimal disturbances yielding the largest

Nonlinear control of unsteady finite-amplitude perturbations in the Blasius boundary-layer flow [PDF]
, 2013 The present work provides an optimal control strategy, based on the nonlinear Navier–Stokes equations, aimed at hampering the rapid growth of unsteady finite-amplitude perturbations in a Blasius boundary-layer flow.

A two-way coupled regional urban–street network air quality model system for Beijing, China [PDF]
Geoscientific Model Development, 2023 Owing to the substantial traffic emissions in urban areas, especially near road areas, the concentrations of pollutants, such as ozone (O3) and its precursors, have a large difference compared to regional averages, and their distributions cannot be ...

The onset of instability in unsteady boundary-layer separation [PDF]
, 1996 The process of unsteady two-dimensional boundary-layer separation at high Reynolds number is considered. Solutions of the unsteady non-interactive boundary-layer equations are known to develop a generic separation singularity in regions where the ...

Impacts of an unknown daytime HONO source on the mixing ratio and budget of HONO, and hydroxyl, hydroperoxyl, and organic peroxy radicals, in the coastal regions of China [PDF]
Atmospheric Chemistry and Physics, 2015 Many field experiments have found high nitrous acid (HONO) mixing ratios in both urban and rural areas during daytime, but these high daytime HONO mixing ratios cannot be explained well by gas-phase production, HONO emissions, and nighttime hydrolysis ...
